Application filed August 13, 191.7. Serial No, 185,838.

' To all whom t may concern:

Be it known. that I, WILLIAM J. Touma- 'roN, a citizen of the UnitedStates, residin in Chicago, county of Cook, and State o Illinois, haveinvented certain new and useful Improvements in Lubricating Mechanism,of which I dovdeclare the fol owing to be a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart 0f this specification.

The present invention while susceptible of more extended use is moreparticularly designed to provide improved means for lubricatin the crosshead gibs or shoes` and guides o a locomotive and the invention consists'in the features of novelty hereinafter described, illustrated intheaccompanying drawings and more particularly pointed out in the claims atthe end of this specification.

The lubrication of the cross head ibs or shoes and the guides of thelocomotlve has heretofore been effected 'by oil in fluid form but thisis foundobjectionable because, unless the oil cups are promptly shut offat the end of each trip or run of the locomotive, they continue to feeduntil the oil is exhausted, thus occasioning needless waste. The objectof my invention is to provide means whereby hard grease can be appliedto lubricate the cross head gibs or shoes and guides in such manner asto avoid waste, while at the same time insuring an effective lubricationof the parts when in operation.

Figure 1 is a plan view of one of the gibs of a locomotive'cross headand a portion of the slide whereon the gib is mounted to travel. Fig. 2is a view in longitudinal section on line 2--2 of Fig. 1. Fig. 3 is -anenlarged view in cross section on line 3-3 of Fig. 1. Fig. i isa View inside elevation of a guide showing the cross head gib mounted thereon,the grease chamber being formed in the guide itself. Fig. 5 is anenlarged view in cross section on line 5-5 of Fig. 4.

Referringto the form of the invention embodied in Figs. 1 to 3 of thedrawings A. designates one of the guides of the locomotive and B denotesone of the cross head gibs, this gib B being ordinarily formed of asingle piece of metal and being provided with suitable means, as forexample, the upstanding anges b having bolt holes therein whereby thegib can be conveniently connected t0 the cross head. The gib B is shownas pro Specication of Letters Patent.

j Patented vided with a liner G which however, forms no part 'of mypresent' invention.

In the body of the cross head preferably about the center thereof, isformedl a grease chamber D which is shown as ex' tending transversely ofthe gib and as provided with interior screw threads d ex tendinginwardly from one end of the chamber. Into the threaded end of the reasechamber D is fitted a correspondingly t readed plug E having a polygonalopening e adapted to receive a key whereby the plug E may be turned fromtime to time to elfect the feeding of the grease from the chamber D. Theinner end of the'plug E is preferably provided with a lug or extension ethat will embed itself in the hard grease and will aid in preventing anyaccidental working loose of the plug E.

From the foregoing description it will be seen that when the greasechamber D is illed with hard grease and the plug E is inserted in thethreaded end of the chamber, the turning -nward of the lug will forcethe grease fro the chamber through the channels or duc s F to thewearing face of the gib B and of the slide A.

Instead of forming the grease chamber in the cross head gib or shoe Bthis grease chamber may be formed in the bod;7 of the slide itself, as shown in Figs. 4 and 5 of the drawings. In this form of the invention theguide A. is provided with an integral grease chamber consisting of acavity D having its outer end interiorly threaded as at d and fittedwith a screw threaded plug E as in the form of the invention shown inFigs. 1, 2 and 3 of the drawing. When the grease chamber is thus formedin the slide A. a plurality of channels oradu'cts F will lead from thegrease-chamber to the wearing face or faces of the slide.

The precise details of construction above set forth may be modiiedwithout departure from the scope of the invention.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. The combination of a crosshead gib and the guide whereon it ismounted, one 0f said parts having an oset integral rease chamberextending transversely thereo said chamber being interiorlyscrew-threaded and being provided with one er more channels eet. ae,isis.

gib B and chambered and screw-threaded t0 form a i grease receptacle,and a plug en aging the threaded portion 0f said receptac e7 suitable l0channels leading from said receptacle to the wearing 'face of the gib.
